Parameters & Programming
C Group – Intelligent I/O and Communication Parameters
This parameter group is used to program the functions of the digital and analog I/O.

U = 60 Hz default settings, K = 50 Hz default settings. Settable using Pb85 – [Factory Default Select]
ATTENTION
• All digital inputs respond to level sensitive commands.
• Inputs do not require a voltage transition (cycle) after a fault condition is cleared, after input power cycling or after
programming the logic of the digital input.
• All digital inputs can be programmed as NO or NC. HOWEVER, The START COMMAND SHOULD BE SET AS NO (ACTIVE
HIGH) AND THE STOP COMMAND SHOULD BE SET AS NC (ACTIVE OPEN). If set opposite of this, an inadvertent start
or failure to stop could occur should a discrete connection be lost or control wire come loose. IF THE USER CHOOSES TO
DISREGARD THIS SAFETY PRACTICE – THE RISK ASSUMED BY THE USER CAN BE REDUCED BY ASSURING THAT
OTHER SAFEGUARDS ARE USED TO INSURE PROPER START AND STOP OPERATION. Depending on the application:
This may include appropriate emergency stops, redundant wiring, electronic guards and/or mechanical guards.
Failure to observe this precaution could result in severe bodily injury or loss of life.
